What is the supply volts? 12 volts
Simple resistor will be fine to run
leds. 470 ohm resistor will work on
leds depending on the voltage of the
led.
Same goes for buzzer. It's about current.
If you look at the buzzer it will tell you what
the current rating is. Ohms law is your friend
or google.
What type of sensor are you using??
